Title: Recovery of non-ferrous metals from zinc residues
Inventor: VAN CAMP MAURITS
IPC: C22B5/10
Filed: 2004-06-08
Abstract: The invention relates to a process for the separation and recovery of non-ferrous metals from zinc-bearing residues, in particular from residues produced by the zinc manufacturing industry. The process allows for the valorisation of metal values in a Zn-, Fe- and Pb-bearing residue, and comprises the steps of: -subjecting the residue to a direct reduction step, thereby producing a metallic Fe-bearing phase and Zn- and Pb-bearing first fumes; - extracting the Zn- and Pb-bearing first fumes and valorising Zn and Pb; - subjecting the metallic Fe-bearing phase to an oxidising smelting step, thereby producing an Fe-bearing slag and second metals-bearing fumes; -extracting the second metals-bearing fumes and valorising at least part of their metallic content. The main advantage of this process is that an environmentally acceptable output for Fe is obtained.

Inventor: DIAMOND MAXIME
IPC: B27B31/06
Filed: 2006-05-04
Abstract: A method and system for monitoring the quality of log cutting either off-line or in real-time is based on optical measurement of half-squared or full-squared cants characteristics as produced at primary or secondary cutting stage, so as to increase the proportion o f high-value wood pieces that can be recovered from full squared-cants produced at the sawing stage. The log is fed lengthwise to a primary cutting station (canter) capable of producing the first pair of opposing cut faces, while guiding the log substantially in a direction of the machine axis. The profile of the peripheral log surface at a plurality of cross-sections along the machine axis is measured to generate corresponding post-cut profile data, from which an estimation of log raw profile characteristics is made, to generate corresponding raw profile data. Then, from post-cut and raw profile data, resulting data on at least one parameter related to the cutting quality of the log. The proposed monitoring system and method provide accurate control of target dimensions, while optimizing the adjustment of other quality related parameters such as faces parallelism and cant centering, as well as to measure the level of some surface defects generated at cutting such as knife marks, stripping and roughness, in order to obtain a more complete performance diagnostic.
